Working Safely with Lead | northernsmelters

Inhalation of particulates, or fine lead dust, has the same effect as ingestion by mouth – it is poisonous. Skimmings or dross should be placed in a closed container, and dross should be minimised by not over-heating or over-stirring the metal. Grinding, cutting or polishing metal containing lead produces fine particles which may be inhaled.
